You can choose between two types of material for your roller, PVC and Aluminium, the difference between the two is the heat dissipation capacity caused by friction with the wheels of your bike.
Aluminium provides better heat dissipation and therefore less wear and tear on your tyres. Aluminium rollers have many advantages, including greater durability and lower noise levels. In addition, they have a triple inner bearing and are easy to clean and totally rustproof, very beneficial qualities in this type of product.
At ZYCLE we recommend the purchase of this roller in case you make a very intensive use of it, but in any case, a very good option would be to opt for PVC rollers.
